or full tube and operatively connected or engagedtherewith after the contents have'been exhausted from one tube or container.

Other objects of the invention are to provide a dispenser of the character described which will be simple in construction, strong, durable, eflicient and reliable in use,'compact, attractive in appearance and which may be manufactured at low cost.

All ofthe foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like c-haracters of' reference designate corresponding parts throughout the several views, an wherein "Figure 1 is a view in vertical section through a dispenser in accordance. with this invention showing, in broken lines, a collapsible'tube or container in position therein.

Figure 2 is a view in vertical section taken at right angles to Figure 1 with atube or container removed.

Figure 3 is a detail view in vertical section through the ejecting mechanism;

Figure' l is a horizontal sectional view taken substantially on the line 4-4'of Figure 1 looking downwardly and with a tube or container removed.

Figure 5 is a view in end elevation of the ejecting mechanism with the rollers removed.

Figure 6 is a detail view inbott'om plan of the rotatable inner cap or closure.

Figure 7 is a detail view in side elevation of the-cap or closure illustrated in Figure Figure 8 is a fragmentary detail viewin vertical section and on' anfenlargedi scale showing the rneans' for mounting the ring gear in thecapwhich is illustrated in Fig.- ures6 and 7.

- Referring to thedrawing a detail, 1mm ,be seen that thereferencemumern,1 designates a substantially cylindrical icasingiof suitable length which is open at its uppeni'en'd and closed 'at 'its lower end, as indicated by removably 'rnoi'inte'd therein adj acent diametrically opposite-sides thereof -a pa-ir 'of longitudinally extendingspac'ed, parallel threaded shafts 3 having reduced, unthreaded-end the reference numeral 2: The casingll has portions' which-"are j ourn'a' led in diametrically oppositesides"of t h'e flat I44 The rings4-ar slida'bly' insertabl'e in the casing' l and are "provided with notches 5 in outer peripheries for'the reception of the inwardly pressed longitudinally eXtending ribs :B- in upper'and lower portions; ofthecas'ing l for retaining the rings against rotation inv the casings I Fixed on the endporti'onsnf each of the threaded'shafts S isa inien gear 7? ZThe shafts'3 are threaded through the-end portions of a substantially r'e'ctang'ular*Inetallic plate 8 having-"an el'ongated opening therein in which a 3 pair of; ejecting r'olls l'9 are disposed for "rotation, said rol ls 9 bein rotatably mounted onthe plate 8i-- like Pressed outw'aidly on the upper portion of the'casing 1 is'a -'circumferentia-l ly extending rib 10. An inner closure or cap ll isre-v movablyand rotatably mounted on the upper end of the casing land has the lower-portion of its skirt or flange portionpressed 'outwardly, asat '12, to-p-rovid'e an' internal channel for the reception of the r'ib 10 for' releasably "securingth'e cap 11 "on the f casing'l in a manner topermit rotation'of' saidcap thereon." The channelled portion 12'of' theskirt or flange of the cap'z ll "is provided with a series'of spaced slits 13 to permit/expansion of saidportion 12'for engaging-thesame over.

A'riiig gear l l'iszrigidly secured in anupper portion, of the: cap- ,11 and meshes with the pinion gears 7 which are disposed uppermost 'in-the casing l'when the cap :11 is mounted in the rib 10 or to permit removal "of the cap.

between the rolls 9 after which the inner cap position on said casing. lhe ring gear 14 may, of course, be secured in position in the cap 11 in any suitable manner. As seen in Figure 8 of the drawing, detents 15 have been pressed from the cap 11 into the ring gear 1% for securing saidring gear in position. The inner cap 11 is provided with a centrally disposed opening 16 for slidably receiving the neck 17 of the collapsible tube or container 18 the lower end portion of which is inserted between the rolls 9 when the tube or container is inserted in the device. It will be noted that the neck 17 is not connected with the cap 11.

. Anouter cap or closure19 ofjthe slip type is removably mounted onthe inner rotatable ,cap 11, the lower or free end of the skirt or flange portion of the outer cap19 contacting the channelled portion 12 of the inner rotatable cap 11. Thetopof the outer cap 19 is spaced from the corresponding portion of the cap 11 to accommodate the upstanding neck 1 In use, the caps 11 and 19 are removed and the tube or container 18 is insertedin the casing 1 through the open upper end thereof, it

being understood, of course, that the rolls 9 are disposed in the lower portion of the device. The substantially flat lower end portion .of the tube or container 18 is inserted 11 is mounted in position on the casing with i the neck 17 of the tube or container projecting through vthe opening 16. A before stated, the ring gear 14 m'eshes'with the adjacent or upper-most gears 7 when the cap 11 is in position. Now, upon rotation of the cap 11 on the casing 1, the shafts 3 will be rotated in a manner to feed or move the rolls 9-upwardly over the tube or container 18, thussqueezin said tube or container between the rofis and ejecting the contents therefrom. It is understood, of course, that the cap 11 is rotatedin the correct direction to accomplish this. It will thus be seen that the desired quantity of the contents of the tube 18 may be conveniently ejected therefrom. v

' To remove and replace the tube from which the contents have been exhausted, the cap 11 is removed and the rings 4 having the shafts 3 and theplate and rolls 9 thereon are withdrawn from the casing 1 through the open upper end thereof and the emptied tube or container'is removed after which the unit and reinserted in the casing. It will thus be seen that the rolls 9 willagain be disposed in the lower portion of the casing ready to receive a full tube or container. Itwill also be noted "that this has been accomplished without the necessity of rotating the shafts 3 in a reverse direction which, obviously, would require conslderable time. .VVhen the the scope of the invent-ion as claimed.
